Between 1982 and 1989, omission of proper reference to our articles was widespread. Most of these omissions were inadvertent, as researchers relied in their bibliographic research on the citations in earlier papers. But some, beginning with the most often-cited article [1]}, were intentional and consistently maintained. The effects were immediate and enduring. Among all the numerous citations in the 23 articles from 1983 to 1990 reprinted in Wilczek's influential 1990 book [2]}, there is just one citation of an article of ours. In the period that followed, this greatly limited awareness of our work by those for whom the book served as a major resource.
